Modify Control (creating a pressure gauge)

Sorry that you did not have a LabVIEW app for that back thenSmiley Very Happy


Another project I did around that dial-laser involved fitting data from another system that would pressurize gauges to various setpoints and use a camera to measure the pointer displacement (I didn't work on this system).  The output from this was fed into my laser to make a custom dial for each gauge, the problem was that its curve fitting routine was some high-order polynomial and each point was forced to be on the curve.  This led to some wacky curves that went way out of the way to hit each one.  Anyway, I had to take the raw data and make a better fit so the dials could be produced.  Fifteen years ago there weren't as many internet resources we have today, and I didn't even think to try writing my own curve fitting routine, so I bought my first National Instrument product - a disk with a bunch of ActiveX objects, one of which was a curve fitter that I used in a VB project.

Yep, looks like I can access that FTP site.....Thanks for the offer on the upload.
I posted my control in the first post, if anyone is interested.

I don't think the presentation can be emailed - it's 50 MB!

 

Can you access and download from the NI FTP site?  If so, I'll upload it there so you can get it.

 

Thanks,

Laura

OK - I've uploaded the file.

 

I think the files are automatically purged from that site after two days, so make sure to download it before then.

 

Thanks,

Laura

thanks Laura, but at 360 bytes/sec download speed, I'm not sure I'll get it in time.
I have no idea why it's so slow....
*edit* looks like it finished, I'll have a look and see if it answers my questions about modifying that pressure gauge.
Thanks kindly,
Darren

Laura,

 

Can you beat up Snyder and get him to post that demo (It should be an on demand web-cast It was a very nice demo).  I'll go beat from the UG site.

Of course If I had looked at the links and searched and poked at the UI interest group documents I would have found it

Hi Jeff, I don't think those are the demo files mentioned in the presentation???

 

For instructions and example files, please see Demo “1 – Control Editing.”

Hey all -

 

After being released from the hospital with a clean bill of health (Laura F. beat me up good, as Jeff requested), I've uploaded the Control Editing demo from the LabVIEW User Group presentation to our FTP site.  As always, files are wiped from the FTP site after two days, so let me know if you don't grab it by then.

Thanks DRock, I appreciate it.
I'm behind the times here - will these files work on Versioni 8.5?
I'm after a solution to making the needle sweep through a scale that is not equally spaced.  if you look at the gauge I posted in the first message - while in vacuum from -30inHg to 0 the scale divisions are different from the 0-30 psig side.  Basically I need to tell Labview where the 0 is, and where each extreme is.......and have each number between make sense.  I can't figure out of that's possible.
Thanks
Darren
